Today MetroPCS, a prepaid service offered by T-Mobile, has rolled out a limited-time discounted price for its unlimited 4G LTE plan. Anyone who signs up between now and April 5th can get set up for $50 a month, a $10 savings off the usual price. There's no pre-planned end date, so you can then take advantage of the lower price for quite a while.

For comparison, T-Mobile offers unlimited data on the same network for $80 a month.

If affordable phones, unlimited 4G LTE data, and no contracts are all things that appeal to you, then today's announcement from MetroPCS may be of interest.

For starters, the pay-as-you-go company announced the LG Motion, a new mid-range device that will run on its 4G LTE network. It didn't give a lot in way of specs, but the device features a 3.5" display, 1.2GHz dual-core processor, and Android 4.0 for $150.
